Example 2-1 A dock worker piles 100 kg of salmon at 10°C into a freezer with a coefficient of performance of 8.6. The compressor delivers 500 W of power continuously. The specific heat of the fish is 2.98 kJ/kg°C. The fish freezes at -2.2°C with a latent heat of fusion of 214 kJ/kg. a) how long will it take for the fish to reach the freezing point? b) how long will it take for the fish to be frozen solid? Solution: a) The rate of heat removal from the salmon is () in in QC O P W = ± ± ( ) 8.6 500W 4300W in Q == ± The total heat needed to cool the salmon to the freezing
